I'm glad I could help and looking forward to the update :-)
IMO the sleep sound feature seems to be something you should analyze whether it's used or not. If not (<5 or 10%?), drop the feature. If it's used, you might want to extend the collection (in the premium version only?), and then the user could download the sounds he/she wants.
- In the app, cut down the introduction texts and steps. It takes like 30 taps to get the alarm started.
- Also, I found the pulse of the focused area (the circle) annoying and distracting when reading the text just next to it.
- Use briefer descriptions of the things in the guided tour(s). Every word you can remove is often an improvement. And, again, get rid of steps. I'd recommend 3-5 steps tops (and entirely!).
- Somewhere you write "Try to tap here to do something..." => Get rid of the "Try to". As a user, I know how to tap - just write "Tap here to ..."
- Make the sound selections (radio button lists) play the selected sound on tap: by default the top entry is selected. When I tap it—as I initially don't know how it sounds–it doesn't play the sound. I have to switch to the second entry and then back to the first one.
- 42 MB is quite large for "just an alarm clock." Most people won't bother, but keep in mind that even in 2017 software should be performant and, if not necessary, not bloated.
Besides these minor points, I have to say that the idea is great! I am really looking forward to use the app tonight :-)
I have some similar issues. Sometimes Firefox lags after loading the page (around 1 sec), but eventually works fluently afterwards. It feels like it needs to warm up the engine.
I noticed that disabling "smooth scrolling" in the settings helps with initial scrolling issues.
However, in general I have the feeling that FF57 is faster than before. Could also be that I now focus on the loading times more than usual. A restart of Firefox helped yesterday after the upgrade to 57.
I have a MacBook Pro 2015 and am Firefox user since 1.0 ;-)
Probably an alternative: you can configure a keyword to a stored search engine. Then you can search like `a lean startup`, where `a` is a keyword followed by a blank for amazon.com.
I found this to be very fast. It's also handy for translations, etc..
